a.) As we begin to think about being active and prepared, explore this website and the links that are specific to your region or area of interest to learn more about health (physical and psychosocial) and environmental impacts or preparedness needs for these disaster precipitators.
My interest is earthquakes. Although I don't live in San Francisco, the earthquakes can affect anywhere around SF, which I am concerned whenever I hear the possibilities of having the earthquakes from the news. There are various resource for the earthquakes in the website; health impacts; psychosocial impact; health recovery. Regarding to psychosocial information, parents can learn the impact of the earthquake in children and how they can support their children after the earthquake. The NCDMPH provides disaster preparedness in children with detail information. They had "Pediatric Disaster Preparedness Curriculum Development Conference" in March 2011. They focused the concerns for children who experience the disaster. This enable for parents to prepare physically and psychologically for their children for the disaster.
b.) In California we have the Disaster Healthcare Volunteers Site, where healthcare professionals and those with healthcare experience can express a desire to be a volunteer should a disaster happen. Is there something similar where you live?
In Santa Clara county, I found "Medical Volunteers for Disaster Response(MVDR)". The people in this group are registered nurses and physicians as well as social workers and mental health professionals. The main three areas that are managed by this team are medical/health emergencies, disasters that cause injury to large number of people, and community outreach. I looked over the package for MVDR. According to the package, their mission is "to improve the health and safety of communities across the country by organizing and utilizing public health, medical and other volunteers to support medical response locally and throughout the State." The members in the team have professional licensure or certification. They need to complete some training. In order to be a member of MVDR, person must be citizen of U.S, able to stand for long periods of time and able to lift up to 25 pounds. It was interesting to know that there are 4 different levels of membership depending on age, interests, professional training, life experiences, level of obligations to other volunteer or paid positions, etc. The highest level is 4 called "leader". They need to attend a 6 training and 2 exercises per year at minimum.
I also found one called "Community Emergency Response Team". They are not medical professionals like MVDR, but they get trained some basic disaster response skills. After training the skills, they are able to help people in community when professional responders are not immediately available to help.
